如何在两个目标节点之间形成不相关节点的Xpath [英] How to form Xpath with irrelevant nodes in between two target nodes
问题描述
我如何使用 Xpath 获取有时在目标节点之间存在不相关节点的节点.
我的 xml 文件通常采用以下形式:
<目标><目标>我想获得的文本</目标></目标><目标2><goal>我想获得的第二个目标</goal></target2><身体>我需要将目标的目标和目标 2 的目标放在单独的字符串中.因此，我使用 Xpath "//body/target/goal" 获得了我想获得的文本"，并使用 Xpath "//body/target2/goal" 获得了我想获得的第二个目标".
非常简单.
但是后来我发现在目标和目标(或目标 2 和目标)之间可能有单独的节点(未知)，如下所示:
<目标><烦人的><目标>我想获得的文本</目标></烦人的></目标><目标2><想法><goal>我想获得的第二个目标</goal></noidea></target2><身体>我仍然需要区分这两个目标，所以我不能只用//goal"来累积目标.我需要什么样的 2 个 Xpath 才能获得我需要获得的每个文本?
非常感谢您提前
在 target/target2 和 goal 之间使用通配符:<预>//身体/目标/*/目标
<预>//身体/目标2/*/目标
How would I obtain a node using Xpath that sometimes has irrelevant nodes in between goal nodes.
I have xml file typically in the form as following:
<body>
<target>
<goal>Text I want to obtain</goal>
</target>
<target2>
<goal>Second Target I want to obtain</goal>
</target2>
<body>
And I need to throw target's goal and target2's goals in separate string. So I got the "Text I want to obtain" using Xpath "//body/target/goal", and got the "Second Target I want to obtain" using Xpath "//body/target2/goal".
Very simple.
However later I found out that in between target and goal (or target 2 and goal) there could be separate nodes (not known) as following:
<body>
<target>
<annoying>
<goal>Text I want to obtain</goal>
</annoying>
</target>
<target2>
<noidea>
<goal>Second Target I want to obtain</goal>
</noidea>
</target2>
<body>
I still have to distinguish the two targets so I cannot just accumulate goal with "//goal". What kind of 2 Xpaths wold I need to obtain each text I need to obtain?
Thank you very much in advance
Use a wildcard between target/target2 and goal:
//body/target/*/goal
//body/target2/*/goal
